What percentage of the earth's surface is covered in water? About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog.

What percent of the earth is land and how much is water? There are generally two versions of the answer to this question. The first is the more general about 70% of Earth is water while about 30% is land (US Geological Society). The second is the more specific 71% of Earth is water while 29% is land. Both will serve, depending upon your need and aim.

What percentage of the Earth's water is drinkable? Two percent of the water on earth is glacier ice at the North and South Poles. This ice is fresh water and could be melted; however, it is too far away from where people live to be usable.

How Much of the Earth is Covered with Water? About 70% of the earth’s surface is covered with water. Ninety-seven percent of the water on the earth is salt water. Salt water is filled with salt and other minerals, and humans cannot drink this water. Although the salt can be removed, it is a difficult and expensive process. Two percent of the water on earth is glacier ice at the North and South Poles.

TRB 4:1 - Investigation 1 - Where is Water Found? 1 Looking at a globe of Earth, describe the difference between how much land you see compared to water. Point out that 70% of Earth's surface is covered by water.  Because water in air was less than one penny, it is not represented numerically. Point out to students that this 0.001% of water in air is very important.

What percent of Earth is water? In simplest terms, water makes up about 71% of the Earth’s surface, while the other 29% consists of continents and islands. To break the numbers down, 96.5% of all the Earth’s water is contained within the oceans as salt water, while the remaining 3.5% is freshwater lakes and frozen water locked up in glaciers and the polar ice caps. Of that fresh water, almost all of it takes the form of ice: 69% of it, to be exact. If you could melt all that ice, and the Earth’s surface was perfectly smooth, the sea levels would rise to an altitude of 2.7 km. Illustration showing all of Earth’s water, liquid fresh water, and water in lakes and rivers.

An Ocean Mystery in the Trillions Water, however, is a different story. It covers more than 70 percent of the earth’s surface and goes down miles. Scientists put the ocean’s share of the biosphere at more than 99 percent. Fishermen know its surface waters and explorers its depths. But in general, compared with land, the global ocean is unfamiliar.

How Much of the Earthâs Water Is Drinkable? It is interesting and quite shocking to note that less than 1% of the water on earth is drinkable. Freshwater. This may come as a surprise for many because water makes up seventy-percent of the Earth’s surface. However, despite the fact that three-fourths of the Earth is made up of water, only 2.5% of this is freshwater, while the rest is in the form of sea water, and is therefore not suitable for drinking. Furthermore, of the 2.5% freshwater supply we have, the majority or 66.67% of this is in the form of ice caps or glaciers, which means that most of this is not available for human consumption.
